About the Job
We are a fusion of former U.S. Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools, false positives resulting in alert fatigue, blind spots, "checkbox” security culture, c...
We're looking for a Webapp Offensive Security Engineer with deep, hands-on web application penetration testing experience to push our autonomous testing beyond what it can do today. You'll be testing real customer web applications — not just labs and benchmarks — using NodeZero as your starting point and then going ...
This is a pentesting-first role. You won't be expected to architect platform internals or ship production features yourself — you'll be the offensive expert who tests live customer applications, finds the gaps NodeZero doesn't yet cover, demonstrates them, defines what "good" looks like, and partners with engineerin...
Key Responsibilities
Please note this job description is not designed to cover or contain a comprehensive listing of activities, duties or responsibilities that are required of the employee. Duties, responsibilities, and activities may change at any time with or without notice.
Required Skills & Abilities
Extensive hands-on experience conducting full-scope web application penetration tests.
Deep, practical knowledge of common and not-so-common web vulnerability classes — SQL injection, XSS (reflected, stored, and DOM-based), SSRF, SSTI/CSTI, IDOR/BOLA, authentication and authorization bypass, path traversal, LFI, and similar — including how to chain them to demonstrate impact.
A talent for finding and exploiting business-logic and edge-case flaws that automated scanners routinely miss.
Strong command of proxy tools like Burp Suite and browser developer tools.
Comfort scripting to reproduce findings and build proof-of-concept exploits (e.g., Python or similar) — you don't need to be a professional software engineer, but you should be able to write and read code well enough to demonstrate an exploit and collaborate effectively with engineers.
Ability to clearly communicate attack steps, impact, and remediation guidance to both engineers and non-technical stakeholders.
Curiosity about emerging AI technologies and comfort using AI-assisted tools in your testing and research workflow.
Strong written and verbal communication, including technical documentation.
Ability to manage multiple priorities, work independently, and mentor teammates of varying experience levels.
Quick to learn and adopt new technologies, frameworks, and target stacks as needed.
History of recognized security research, including documented CVE discoveries and responsible disclosure.
Track record of successful bug bounty contributions.
Familiarity with how autonomous, agentic, or AI-driven pentesting tools work — and a sharp instinct for where and why they fail.
Experience writing detection or attack content (e.g., Nuclei templates, sqlmap tamper scripts, custom Burp extensions).
Enough software development background to collaborate fluently with engineers on remediation and product coverage.
Familiarity with relational and graph databases, particularly Postgres and Neo4j.
Experience with AI/LLM tools for building agentic workflows (e.g., LangChain, LangFlow) and integrating contextual data using protocols like Model Context Protocol (MCP).
Outstanding problem-solving aptitude and a relentless curiosity for how things break.
Self-motivated and highly energetic, with the ability to operate effectively with limited supervision and guidance.
Work with our engineers and security researchers to turn manual discoveries into reliable, production-safe product capabilities.
Strong technical documentation and communication skills.
Document findings, methodologies, and recommendations for both technical and non-technical stakeholders.
A portfolio of novel web application research, exploits, or edge-case findings you can walk us through.
Demonstrated examples of using AI to enhance or accelerate your testing and exploit development.
OSCP, OSWE, or comparable offensive security certifications.
